Great catch! ✅
This fixes the model reference mismatch between backend and frontend:
- Backend:
claude-sonnet-4.5(ID:claude-sonnet-4-5-20250929) - Frontend was using:
claude-sonnet-4❌
Changes verified:
- Updated both Claude and Cursor entries in MODEL_FALLBACKS
- Aliases match backend model IDs
- Aligns with commit a80d32b ("Update model references to Claude Sonnet 4.5")
Your suggestion about fetching models from backend API is excellent - that would create a single source of truth. Consider opening a follow-up issue to track that enhancement.
Ready to merge!

Problem
Claude Sonnet 4.5 was not displayed in the chat input section.
Root Cause
Mismatch between backend and frontend model references:
claude-sonnet-4.5(model ID:claude-sonnet-4-5-20250929)claude-sonnet-4Changes
Updated MODEL_FALLBACKS in chat page to use correct model ID and aliases for both Claude and Cursor CLI configurations.
Confirmed models are working
Suggestion
To prevent future mismatches, the frontend should fetch model configurations directly from the backend API instead of maintaining a separate hardcoded list. This creates a single source of truth and ensures consistency. Happy to implement this if you'd like.
